"Clutch Hot Warning"... but I'm stumped as to why?

I am showing a buddy how to off-road in a manual in my truck.

My buddy and I spent a total of 15 minutes "off road" yesterday. We made it to the little spot I wanted to go to, and while the driving wasn't as smooth as it could have been, he practiced getting it in 4 wheel drive, and for about 30 second it was in 4 low, 1st Gear, RPM never exceeding 2k. In 4 wheel drive, there was definitely some clutch riding going on because he couldn't find the bite, but nothing that I am concerned about as it was probably 5 minutes total with intermittent clutch riding. I'd equate it to no worse than "beginner stop and go traffic" type manual driving.

He got uncomfortable, so I got in the drivers seat. The opening we were in narrowed down, so while in 2 wheel drive I began a multi point turn, and it turned to mud, so I backed up enough to get out, and in order to back up I had to give it a bit of gas. I completed one more forward, then a second backward adjustment to get pointed in the right direction. Then I got the dreaded "Clutch hot warning- release the clutch and let it cool down" message. Well, I was not willing to get stuck in the mud, so I put it in 4HI, clutched on more time to get back into 2Hi, and we left the area, with minimal clutch use on a 2WD easy exit out of the area.

2 minutes later, the warning was gone.


I then got to thinking perhaps the clutch was being ridden the whole time he was driving, and he said he didn't think so- he had his foot near the clutch, but the clutch was "fully let out" when he was advancing/driving. I know this isn't ideal, and while it should be avoided, that short amount of time isn't really going to hurt anything.


A few key points- we never smelled clutch burning. I think outside of a grand total of 30 seconds combined of "riding the clutch", it was actually a pretty easy ride.

So the big question is (and obviously just assuming everything I said here is accurate), is there an actual temp sensor on the clutch? Or did I just create some sort of pattern that would indicate that I was reasonably going to damage the clutch if I kept on doing the same thing I was doing prior to the warning popping up. And the supplemental big question is "what is the likelihood that had I not reversed (which is not a fun thing to do even on flat ground in this truck) I would have seen that message?"

Any thoughts on this would be welcome.

Don't know the answer to your question but wanted to make sure you are aware of the clutch recall for overheating.

Thanks. I am. I'm a bit disappointed in that, because I figured that would be a risk after meaningful amounts of time on rocks- not after 15 minutes and going into reverse twice.

I never thought I'd say it but dammit if I'm not thinking about investigating a trade in if the assembly is going to be that finicky.

Hopefully the recall fixes it. I'm not sure what is going on beyond the fact that there is a recall as I have an AT.

You should be fine, I believe latest fix to manual was to add the warning way before any damage happens. There is an ongoing recall as Bobchadwickga stated, but most dealers are short on parts, with no clear guidance from Jeep on how to proceed. Personally I won’t be doing any off reading or towing till I know my local dealer can fix the truck in a reasonable amount of time. If this is your DD, there is nothing worse than $40k plus paper weight in your garage. On the bright side you will be getting a brand new clutch for free… eventually

Ok, good to hear. I guess I'd much rather have the "we need you to baby this" warning too soon than too late.

Still a bummer to have a recall with no end in sight. I also really, really, really don't want to give up the manual. I'm happy to pay extra to get re-geared, and lockers, and all of the other expensive fun crap, but if the clutch isn't going to work that just kills the vibe.

Worst case if you are happy modding, which it sounds like you are, there are two great aftermarket clutch options if it ever becomes an actual issue. Regardless of what Jeep comes up with the for their "fix", I'll be getting one of these one day. But for what it's worth, so far no issues with my stock clutch, knock on wood ha.

I wouldn't bet all your money on that happening. Maybe, but maybe not as well. Never underestimate the bean-counters and their ability to present even more non-viable solutions that still won't fix the problem all in the name of saving them some money.

I went with the centerforce clutch and high inertia flywheel and am loving it. I still am not a big fan of the 6 speed gearing for a truck. It seems the transmission is more for a car than a truck, but soon we'll all be driving electric with 1 forward gear.

I agree- I actually traded it in a couple of days after this issue occurred when the guidance from Stellantis came back and said something along the lines of "Our solution for the recall is in. Ultimately, this will reduce engine power to prevent issues". I don't want a further-neutered truck when I already sacrificed a bunch of towing capability just to say I was driving a manual.

Time for an ACT Clutch

"Just a follow up from the first tank of fuel. The clutch feels great, much more natural. The heavy flywheel makes the truck carry speed better on road and is much less jerky in general. Overall a GREAT upgrade to the JT

On road the clutch/flywheel is great, but off road is where it really shines. It'll idle over rocks and through obstacles without even a hiccup.A vast improvement of the stall prone factory set up. Overall, very happy, and I will suggest it to anyone who complains about their JL/JT 6 speed. I would go as far as to say it even makes up for the odd gearing spacing that people complain about on these trucks. "

Not sure if this is do to overheating but this Mopar mechanic shows a fried clutch plate they are working on.
